This invention relates to `elevators and ele- Avator inclosures and has among its objects the provision of an improved type ofl elevator and an improved type of inclosure for elevators. These improvements in elevators and elevator inclosures, while capable ot'inany "different uses, are particularlydesigned for use in the modern ofce buildings, lofts, hotels, stores and other buildings having' consid'- Ierable tiaiiic to and trom the ground floor and' also betweeiithe various floors.

Inl buildings of' he types just referred to the problem of liandling'the trailic speedily and with a minimum of confusion is a serious one. As elevators are constructed at the pres? ent time it is necessary, when an Velevator stopsat a floor, for the persons Vdesiring to board the elevator to wait until all persons within the elevator desiring to get off succeed in getting` oli, after pushing their way to they frontoi the car. This slows up the movement of the v"elevators and causes a great deal ofy an-y noyance to the passengers, particularly in cases' Where collisionsoceurbetween those 'trying to get in and those belatedly trying to get out. i -v f f Toovercome this objectionit is vmy intention to construct an elevator having an enin thetwo directions will be dividedg thereby eliminatingl thepresent confusion. 'It/is also my intention to provide the elevator inclosure with double means oi access toeach elevator at each floor in correspondence with the provisions made on the elevator 4itselii Another object of the invention isto'pro- Avideanelevator which will give the attendant or operatorfgreater-ifree'doin from inter.- =ference from passengersinhis manipulation of the car and the various controlling devices.

A further objectoff the invention is to provide means for opening and closing 'both elevator doorsor gatessimultaneously and yalso both inclosuredoors either simultaneously or selectively, thereby enabling the attendant to specific construction and arrangement', of the tion progresses;

and movable' .relatively to the elevator cage and into operative relation to rocker arm 44.

A suitable device for this lpurpose is indicated at 45, "which represent what is commonly known as a cam or -shoe Which may beprol jected into engagement Withl rocker armj44fv upon arrival ofthe elevator 1 at ithe landing, the projection of the cam-being effected by pressure on the toot pedal 40 iny the manner f clearly illustrated and explained in kpatent to yBassettut1,601,841, granted Oct. 5, 1926, and Y l t Ivided in the elevator 1 to assurethe operator in patent to Randall No. 1,347,711 granted July 27, 1920. Referring to Figure 'of the drawings accompanying this specification such a suitable mechanism as applied to the shoe or cam 45 Would'comprise preferably a bracket 75, rigidly fastened to the roof-of the car, on which-the cam 45 maybe made vtransversely movablethrough the provision of suitable links such as'76., to which may be connected at the outer 'endthereof a 'suitable vertically disposed actua-tingrod 77 eX- -tcnding downwardly to a point preferably beneath the floor of the elevator, at Which point actuating means may be provided in theform of a-bell crank 78, ahorizontally disposed rod 79,'andasecond bell crank 8O having one end VAoperativelyconnected with the rod: attachedto the operators .footpedal 40. With suchy an arrangement it is obvious that When the pedal `is depressed against the lnormal tendency of spring 81 such depression and consequent movement of the bell crank 80 and rod 79 Will cause a corresponding` movement, of the vertically disposed rod 77 and a corresponding outward" projection of the cam 45, 'thereby imparting motion to the valve operating links 44 and 41. Inasmuch as the projection Vof cam may -be accomplished in a variety of other Ways and'thru any suitable mechanical link motion, further explanation of this particular feature of the operationfis believed It is to be understood of course that the saine means which produces theprojection of cam-45 may also produce actuation of thev valve controlling the vmotor mechanism forA opening and closing gates 4 and 5 of the elevator.. With suoli an arrangementv the operator of the elevator Would initiate the operation of both sets of doors simultaneously and by a single motion on his part. l i

Means are provided, as illustrated in Figure 5, to permit manual opening of-gates4 and 5 simultaneously in the event of failure of, or` omission to suuply, power operation vfor thesegates. SuchV manual control preferably ,comprises a pair of fleXiblecables. or

ropes, as indica-ted at 13 and 14,-attached tos' the vertical bars vot thegates 4 and respectively, as indicated, and converging at 15, vWhere theyarebrought together to-orm a single rope or chain, which can begrasped by thepoperator. With such an arrangement it I is possible lioi the operator 'to effect opening ber 16 and then locking the usefo'f the catchshown ati17i'y Y c To assist ingtheclosing movement ot' .the gates 4 and 5 the. gates are shown as provided With' a sloping guidevvay both at ltop "and bottom, as indicated in Figure :5, so that their .oWn-We.ight, When permitted to act, aidslin returning them-to 'closedposition Y As shown at Figure 1 a barrierj39 is proor attendantv againstinterference from occupants of the car.
